Abstract

A wind turbine blade (100) comprising a blade body (102), at least three electrically conductive elements (112, 114, 116, 118, 122, 200) comprising conductive material, said conductive elements optionally comprising at least one lightning conductor (112), at least one spar cap (114, 116), and at least one heating arrangement (200), and a potential control arrangement, wherein the at least three conductive elements have longitudinal axes that are essentially codirectional with a longitudinal axis (Z) of the blade body. The potential control arrangement comprises a plurality of coupling devices (126, 128), each of which coupling at least two of said conductive elements, each coupling device being positioned at predetermined locations (130) with respect to a blade axis being a longitudinal axis of the blade body. At least a first portion of said predetermined locations are terminal locations based at least on locations of structural discontinuation regarding at least two of the conductive elements, the first portion comprising at least one terminal location relating to a first conductive element and at least one terminal location relating to a second conductive element. At least a second portion of said predetermined locations are within a selected maximum distance from a terminal location or within a selected maximum distance from an adjacent predetermined location.
